Mastering TypeScript 3 - Third Edition

Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Backbone testing

In this section, we will take a look at the tests we will need to write to cover the required functionality of our Backbone sample application.

Test setup

One of the benefits of writing applications in Backbone is that the framework itself does not have many dependencies. To run a Backbone application, we need to have loaded the Underscore library, the jQuery library (or equivalent), and the Backbone framework itself. Once these libraries have been loaded into our browser, we just need to include all of the files that we have written for the application. By way of an example of this, let's take a look at the <head> tag in our index.html file as follows:

    <link rel="stylesheet...
